  • In the past few years, reports of transgene migration from agricultural to wild populations have begun to emerge.
  • transgene escape
  • selection favoring a transgene
  • spread of transgenes

Examples

  • Thus, once transgene escape has been detected, the question is, has it progressed beyond the F1 stage?

    Academic text (2008)
  • Moreover, suppose that at generation t, the transgene occurs in the adults of the wild population of interest at some nonzero frequency.

    Academic text (2008)
  • We have discussed the major types of population genetics approaches available for studying the dynamics of transgene escape.

    Academic text (2008)
  • Such actions may substantially reduce transgene introgression and population-level effects.

    Academic text (2008)
  • Random integration of the transgene into individual cells can yield wide fluctuations in the expression levels and patterns of regulation.

    Academic text (1992)
  • There is also concern that transgenes may increase allergies through the introduction of new proteins to foodstuffs.

    Academic text (2001)
  • There has been little discussion about how to apply population genetics methods to monitor the spread of transgenes that are detected outside the agricultural populations where they are deployed.

    Academic text (2008)
  • The integration of transgenes by homologous recombination alleviates secondary problems caused by endogenous gene disruption in transfected cells.

    Academic text (1992)
  • As previously reported, the Col2.3-11bHSD2 transgene is exclusively localized in osteoblasts and osteocytes by immunohistochemical staining (26, 27).

  • The scientist introduced a transgene into the corn plants to enhance their resistance to pests.

Morphology

transgene = gene (semi-transparent) = trans + gene + trans

Formally composed of 'trans-' + 'gene' and conveys the idea of a transferred/introduced gene, but the technical, laboratory sense ('artificially introduced') may not be fully recoverable by an average B1 learner.

Etymology

Transgene mixes trans- 'across' (as in transport or transfer) and gene 'a part of DNA that helps decide traits'. So a transgene is a gene moved 'across' into another living thing, which is why the word means a gene that scientists add to an organism's DNA.
